Intraband, LLC was established to develop QCL products exploiting the bandgap engineering capability and product reliability provided by MOCVD growth. Working together with the University of Wisconsin-Madison, the company has developed new QCL technologies that enable high-power, high-efficiency, reliable QCL operation with excellent beam quality. The management team includes Professor Dan Botez, Professor Luke Mawst, and Rob Marsland who serves as President.
Key Intraband technologies, exclusively licensed from the Wisconsin Alumni Research Foundation (WARF), include QCL design approaches the team has used to achieve state-of-the-art, multi-Watt CW and peak-pulsed powers from MOCVD-grown QCL single edge emitters. The company also has technologies for surface emitting and coherent arrayed QCLs.
Intraband is based at the University Research Park in Madison, WI, with research operations carried out there and at the Reed Center for Photonics at UW-Madison. These facilities include the Metal-Organic Chemical-Vapor Deposition (MOCVD) equipment and processing labs critical to QCL fabrication as well as equipment for mid-infrared (4-12 µm) laser characterization, life testing, and failure analysis.

Intraband’s Phase II.5 STTR Program achieves coherent single-longitudinal-mode output from a surface-emitting QCL
The achievement of a coherent, single-longitudinal-mode, surface-emitting beam was presented at Photonics West 2020 and published in the SPIE proceedings.
Intraband announced today that it has received a Department of Defense (DOD) Navy STTR Phase II contract to develop quantum cascade lasers (QCLs) with 40% wall-plug efficiency for the mid-wave infrared (MWIR) wavelength region.
Intraband, a quantum cascade laser (QCL) manufacturer, announces an exclusive licensing agreement with the Wisconsin Alumni Research Foundation (WARF).
